Ribbed steel bar surface treatment device

The invention relates to the technical field of reinforcing steel bar machining, in particular to a ribbed reinforcing steel bar surface treatment device. A through groove hole is formed in the conveying frame, the mounting frame is arranged on the outer side of the conveying frame in a swinging mode through connecting plates on the two sides, a plurality of grinding pieces are distributed at the bottom of the mounting frame in an array mode, and the positions of the grinding pieces are matched with the positions of the grinding rods; one end of the rotating shaft penetrates through the conveying frame and extends out of the conveying frame, and a power transmission structure is fixedly installed at one end of the rotating shaft. Steel bars roll in the conveying frame, the steel bars are blocked through the grinding piece arranged at the upper end, meanwhile, when the grinding rod at the bottom rotates, the steel bars are driven to rotate so as to make contact with the grinding piece, and after the grinding p
